In unmarked patronyms

Clerethyn 1; probable identification, Woulfe p.236 has this without the diminutive suffix.

Críodán

Cridan 1; OC&M p.62

Donnchadh

Doneheved 2; Woulfe p.352. Also: O Donohid. See also: fil. Doncoun, O Donked; McGonauthy, McConauthey, Conauth[...]. If the last is interpreted correctly, it cannot be classed as "unmarked" as it must be a reanalysis of a "mac" form.

Fionnbharr

ffynover 1; OC&M p.101

Gerard

Gerard 1; R&W p.189.

Godfrey

Godfrey 1; R&W p.194.

Griffyn

Griffyn 1; R&W p.206. Also: McGriffyn.

Hywel

Howell 1; Welsh, R&W p.241.

Laurence

Lauerance 1; R&W p.272. Also: filia Laurencii.

Lorcán

Lorcan 1; OC&M p.124. Also: McLorkan.

Maolruan

Moltron 1; Woulfe p.612 notes "Meldron" as an Anglicization of "ó Maolruain" so this is not as improbable as it might seem.

Moénach?

Mouenath 1; O'Brien lists this. I can find nothing closer.

Niall

Neele 1; OC&M p.145.

Owain

Ywein 1; Welsh, R&W p.333, but possibly instead Irish "Eoghan".

Patrick

Patrik 1; R&W p.341.

Rambold

de Rembold 1, Rembold 1; R&W p.370. Based on the name's origin, the "de" cannot be locative in sense. While it is found in France as a patronymic marker, this seems unlikely here. More likely, the "de" has acquired some other sense, perhaps having to do with the social status of the family.

Torcall

Torcell 1; compare Woulfe p.411 "mac Thorcaill".

Tuaith(ach)

Toyte 1; uncertain, but see Woulfe p.654.

Names Appearing in More Than One Type of Patronym and/or as a Given Name

The meanings of the descriptive bynames mostly have to do with coloring
(buide, ciar, donn, fionn, ruadh,
rút) or size/age (becc, beccán,
mór, óg), but there are a couple ouside these
groups (faol, reannach). The overwhelmingly most popular
descriptive byname is becc, accounting for over half the
examples. The number might be cut in half if duplicate references to the
same person were eliminated, however the name would still be the runaway
favorite. The only descriptive byname found referring to a woman is
óg.
